What is Quality Control?

Quality control is the measurement of the actual quality of a given program and diagnosing errors. Adhering to QC best practices is the most effective way to avoid quality issues. Quality control services include quality checks that are conducted either at the manufacturer’s factory, known as on-site inspections, or off-site checks done away from the factory. Inspections for soft lines and hardlines are conducted according to the internationally recognized ANSI/ASQC Z1.4 (ISO 2859-1) statistical sampling procedure. During product inspection, the frequency and severity of the defects discovered, and tolerances are analyzed based on standard AQL (acceptable quality limits) to award a pass or fail. The tolerance level is agreed upon by the producer or supplier and highlighted clearly in the quality control checklist used by QC inspectors during the process. Inspections like PSI, quality checks, and audits are all combined and undertaken methodologically in Quality Control Chain. To ensure the accuracy of QC results, you need to choose the right quality control inspector.

A quality control (QC) checklist, also known as the inspection checklist, is a criteria sheet to clarify product requirements. Five key elements should be outlined extensively and clearly in your quality control checklist:

Product requirements: To avoid confusion, product requirements should specify materials to be used, and specifications like weight and dimensions. You can include a sample with the color for comparison. For electronics, including labeling and markings like CE mark.

Packaging requirements: An effective quality control checklist clarifies how the products should be packaged, including weight, dimensions, and labeling requirements like size, contents, and markings. Labeling is particularly important if the cartons convey your brand.

On-site quality checks and tests: To avoid non-compliance and quality issues, you should list the tests and inspections, outline tolerances, and specify pass/fail criteria.

Defect classification: It is used to determine whether the product passes or fails the inspections. Defects under AQL standard are classified into three types – minor defects, major defects, and critical defects that should not be tolerated.

Constructive collaboration between all parties in a quality control chain is vital for success. You have to outline how all parties will collaborate during the inspection and start by consulting your supplier and QC staff as you develop your QC checklist.

The other types of quality control services include QC checks, QC audits, and quality assurance.

Quality Control Testings

Quality control checks are conducted both on-site and off-site to determine whether the product meets the Acceptable regulatory requirements, or satisfies the client’s product specifications. QC inspectors conduct initial production checks and container loading checks as part of on-site quality checks during product inspections. Quality control checks also include on-site and off-site lab tests.

On-site quality control lab tests

On-site lab tests can highlight the raw materials used on your product. QC inspectors can test for hazardous chemicals to ensure your product does not violate regulations or pose safety risks.

Off-site quality control lab tests

A sample is collected and sent to a well-established lab for advanced testing like functionalities, usability, and safety.

Off-site lab tests are useful in quality control checks and ensure your products conform to safety regulations.
